HADEES - ~

At the end of the Battle of Yarmuk, the King of Rome began to ask his
defeated army: "Shame on you, tell me about those whom youfought. Are
they not men like yourselves?" They said,"Yes O King." He said,
"Whowas greater in number, you or them?" They said,"We are greater
than them in every place." He said,"Then why have you been defeated?"
An elder from their great heads said,"They have defeated us because
they stand to pray at night, they fast during the day, they fulfill
their oaths and they are just amongst themselves."
[Ibn Kathir's 'al-Bidayah wal-Nihayah']
